Technical parameters of crawler pneumatic water well drilling rig
1. Large drilling diameter, deep drilling, fast footage, flexible and efficient. It is equipped with large torque hydraulic motor and large bore hydraulic cylinder propulsion, and * * * pump set design, which is convenient for maintenance.
2. The drilling rig adopts excavator crawler chassis, with strong off-road ability, independent modular design and superior mobility.
3. The combined positioner can be adjusted and replaced according to different types of drill pipes and impactors to ensure accurate positioning and centering.
4. The chassis is equipped with four high-strength hydraulic high legs with strong bearing capacity, and the support height of the legs can reach 1.5m. The loading and unloading vehicle can reduce the lifting cost, and can be used as a leveling and stabilizing drilling rig during operation.
5. The winch mechanism facilitates the hoisting of drilling tools, reduces the labor intensity of operators, saves time and labor.
System composition
1. Power system, equipment that provides energy for the whole set of drilling rig;
2. Working system, equipment for working according to process requirements;
3. Transmission system, equipment for transmitting, conveying and distributing energy for the working unit;
4. Control system, control all systems and equipment, and coordinate and accurately work according to the process requirements;
5. Auxiliary system, equipment to assist the main system.
